Gruber Standard Powder/Granule Ground Hopper

Our standard auger-driven transport system Ground Hopper provides reliable conveying of powders such as calcium carbonate blends, ATH blends, as well as granules and other fine particle or lightweight fillers to fill the metering hoppers of Autocaster™ and Batchmaster metering machines. Does not include self-metering. Optional Control systems can be added for additional capability.

  • No overhead mountings
  • Eliminate waste
  • Precise metering available
  • Eliminate laborious manual bulk powder handling and tank filling
  • Stationary or mobile versions available!

Used in conjunction with Gruber Autocaster continuous casting machines or Batchmaster automated metering systems.

Bulk filler handling systems can be integrated with your continuous casting system, and metering or batching systems to reduce labor cost, improve production efficiencies, reduce wastage (material cost), and likely reduce overhead costs.

This Standard Powder Ground Hopper is most often used in conjunction with our Autocaster continuous casting systems, or the Batchmaster metering systems - delivering bulk filler powder or fine granules as needed to the metering hoppers of the Autocaster or Batchmaster. Both Autocaster and Batchmaster include a sensor that when the material level runs low, a signal is sent that turns on the Ground Hopper, which begins filling the metering hoppers atop the Autocaster or Batchmaster machines, Once the high sensor indicates the metering hopper is once again full, it suspends delivery flow from the Ground Hopper until the next signal is given. This system does not include self-metering features that may be required of some batching applications.

Features:

  • Controlled by Autocaster via umbilical connection
  • Stationary ground placement, with optional mobile version or mobile retrofit available. No overhead mountings.
  • Mobile version available with wheels - or upgrade the stationary standard ground hopper with upgrade kit.
  • 50 lb (23 kg) per minute output capability (calcium carbonate or equivalent volumes) depending on specific gravity of filler material.
  • Transport auger constructed from carbon steel, standard 4" (101mm) pitch (i.e. pitch = distance between flights); choice of 45 degree (standard configuration) or optional 60 degree incline. Custom auger configurations available upon request.
  • Overall height 57.5” x 42.5” x 45” (146cm x 108cm x 114.3cm) (LWH) excluding auger
  • Large, rugged 15 cubic foot (0.42 cubic meter) capacity bin constructed of 12-gauge carbon steel
  • Powerful 1 HP 120/230/460 volt motor; upgrade up to 3 HP maximum
  • Sealed dust tight drive and idler bearings with transmission ratio of 20:1 (standard)
  • Pneumatic vibrator for anti-bridging control
  • 2-way forklift entries for convenient positioning
  • Includes screen for reducing introduction of bag scraps and other debris from reaching auger
  • Includes chain clamps for securing bulk bag hopper support
* Weight depends on specific gravity of material.

Ground Hopper Options

Options for increasing the capacity and production run times for your system include these upgrades or accessories: Bulk Bag Suspender Frame, Pneumatic Powder Pump Ground Hoppers, Bulk Bag Gantries, and other items. Review all Bulk Filler Handling related products here.

Ground Hopper with Bulk Bag Suspender mounted

Add a Bulk Bag Suspender Frame to your Ground Hopper!

Ground Hoppers can accommodate either bulk bags (super sacks) or individual bags of filler, as well as other granular substances for even greater efficiency. A recommended option is the Bulk Bag Suspender Frame, which sits atop the Ground Hopper. A Bulk Bag/Supersack is lifted up where the corners of the bag are hung on the four heavy-duty hooks built into the Bulk Bag Suspender Frame, and the bag is suspended above the Ground Hopper - where filler is gravity-drained down into the Ground Hopper as the hopper empties, thus adding to the capacity and length of time you can run a production run. With the Bulk Bag Suspender, you can even keep the filler supply feeding the casting system continously by loading a new Bulk Bag into the Suspender Frame each time it empties, but when you still have powder in the Ground Hopper. End frequent stops by keeping your bulk fillers continuously supplied with a Gruber Ground Hopper and Bulk Bag Suspender Frame.

Mobile Ground Hopper

Easily move your Ground Hopper with this mobile upgrade

A mobile upgrade is offered for all Gruber Ground Hoppers that allows you to move your Ground Hopper to where you need it. You can purchase the mobile upgrade as an option to upgrade your existing Ground Hopper, or purchase a complete mobile version Ground Hopper to begin with.

  • Buy a Ground Hopper with built-in mobile capability
  • Buy a Mobile Upgrade Kit to convert your existing Ground Hopper to a mobile Ground Hopper - #1000CA
 
Pneumatic Powder Pump Ground Hopper

Look at Pneumatically driven Ground Hoppers:

Ground Hoppers can be purchased or upgraded to use pneumatic pressure to transport lightweight fillers from one location to another location. Free up critical space near your casting or batching machine by moving your Ground Hopper to a less space intensive location and using pneumatic powder pump to transport lightweight filler over greater distances.

Note: Please refer to Pneumatic-Transport Powder Ground Hoppers for more details.

Ground Hopper Accessories

Gruber Ground Hoppers accommodate either bulk bags (super sacks) or individual bags of filler. The Ground Hopper is one element of a complete bulk filler handling system. Gruber offers a number of other bulk filler handling accessories further automate or customize its integration into your workflow:

Hangs a bulk bag above a Ground Hopper - doubling the capacity of the Ground Hopper. The Bulk Bag Gantry aids lifting of bulk bags into position (over the bulk bag suspender). Two sizes - 10’ or 15' Bulk Bag Roller Conveyor easily transports super sacks to the ground hopper. Accessory to a Bulk Bag Gantry to lift/suspend the Bulk Bag.
